This paper examines the effects of expanding access to credit on the decisions and welfare of households. I focus on the entry of Banco Azteca, the first bank in Mexico targeting households from the informal sector. Panel data suggests that informal households in municipalities with Banco Azteca experienced several changes in their saving, credit and consumption patterns. In order to estimate t...

Observations in the Lake Powell area have indicated that a significant visibility impairment often exists in this area located in southern Utah and northern Arizona (a schematic illustration of the area is provided in Figure 1). Since several National Park areas within this region are mandated by federal legislaton as Class I areas under the Prevention of Significant Deterioration (PSD) of the ...

PURPOSE The purpose of this systematic review was to critically evaluate the available literature exploring the role of the hip joint capsule in the normal state (stable) and pathologic states (instability or stiffness). Furthermore, we examined the various ways that arthroscopic hip surgeons address the capsule intraoperatively: (1) capsulotomy or capsulectomy without closure, (2) capsulotomy ...

BACKGROUND The current method of treatment for persistent internal rotation due to the medial rotation contracture in patients with obstetric brachial plexus injury is humeral derotational osteotomy. While this procedure places the arm in a more functional position, it does not attend to the abnormal glenohumeral joint. Poor positioning of the humeral head secondary to elevation and rotation of...

A robust procedure to estimate nonlinear mechanical properties of thermally sprayed (TS) ceramic coatings is introduced. Such a method is valuable particularly for TS coatings since each may possess unique properties depending upon its processing condition. Traditionally, their responses have been assumed as linear elastic (isotropic or anisotropic) except in very high temperature environments ...

Barium stars and technetium-poor, extrinsic S stars are binary systems with a white dwarf companion, and with orbital elements similar to those of symbiotic systems. One may thus wonder whether these various families of binary systems involving red giant stars are somehow related. This question is actually twofold: (i) Do barium and binary S stars exhibit some symbiotic activity? (ii) Do symbio...

In the absence of any published information on the indications, frequency, and outcomes of revision augmentation/mastopexy, an 8-year retrospective review was undertaken of all patients undergoing revision of a previous augmentation/mastopexy in the senior author's practice. The data collected included original implant type, location and mastopexy type, indication for revision, interval from or...

A cute traumatic posterior glenohumeral dislocations are rare; they are typically caused by high-velocity trauma, epileptic seizures, or electrocution. Anterior impression fractures of the humeral head (reverse Hill-Sachs defect) occur in over 80% of individuals following a posterior dislocation of the shoulder. The size of reverse Hill-Sachs defects varies and has been reported to be as large ...

Background Arthroscopic stabilization is the most broadly used surgical procedure in the United States for management of recurrent shoulder instability. Latarjet coracoid transfer has been considered a salvage surgical procedure for failed arthroscopic repairs or cases of significant glenoid bone loss; however, with recent literature suggesting reduced risk of recurrent instability with Latarje...
